HUB-ATTACHIN G DEVICE.

Specification of Letters Patent.

Patented Aug'. 20, 1907.

Application led February 21, 1907. Serial No. 358,715.

Io all 'whom it may concern.'

Be it known that I, JAMES W. MARLEP., a citizen of the United States,residing at East Bend, in the county of Yadkin and 'State of NorthCarolina, have invented cei'tain new and useful Improvements inHub-Attaching Devices; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in devices for attaching the hubsof vehicle wheels to their spindles without the use of nuts. v

The object of the invention is to provide a simple, durable andinexpensive device of this character, by means of which the wheel hubmay be quickly and easily locked to its spindle or removed therefrom forcleaning, repairing and lubricating purposes.

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of devices hereinafterdescribed and claimed.

In the accompanying drawings, Figure l is a sec tional view through avehicle hub showing my improved device for securing it to the axlespindle; and Fig. 2 is a perspective view of my improved hub-attachingdevice.

My improved attaching device has a cap l, which is adapted to be placedand to fit snugly in the outer end of the wheel hub a, and is providedwith a central opening and with pairs of lugs 2, which are arrangedaround the said opening. Arms 3 have their outer ends pivotally-mountedbetween the pairs of lugs 2 by pins 4 and are provided at their innerends with segment-shaped jaws 5, adapted to engage an annular' groove bnear the outer end of the axle spindle c, so as to lock the hub to thesaid spindle while permitting it to revolve thereon. The sleeve orboxing is indicated at d.

An operating rod 6 extends through the central opening in the cap l andis provided at its outer end with a knob 7. To the inner end of the saidoperating rod is secured a head 8, which is provided with openings 9,through which the arms 3 extend. Each of the said arms is provided witha curved or otherwise suitably shaped cam portion 9 having an inner facel() and an outer face ll, and the openings in the head 8, through whichthe said arms extend, enable said head to engage either of said camfaces according to the direction of movement of said head. A spring 12which is here shown as a coiled extensile spring is' employed tonormally move the head 8 inwardly and cause said head, by coaction'withthe outer cam faces of the arms 9, to move the free ends of the saidarms inwardly so as to engage their segmental jaws with the groove Zz ofthe axle spindle. The said spring l2 is placed on the inner portion ofthe operating rod 6 and bears between the head 8 and the 'cap l.

In oi'der to detach the hub fi'om the axle spindle, it is only necessaryto draw the operating rod 6 outwardly by grasping the knob 7 thereof, soas to cause the head 8 to move outwardly with said rod. As the said headthus moves outwardly, it engages the inner cam faces 10 of the arms 3and hence moves the free ends of said arms outwardly and thereby causestheir segmental jaws to move outwardly from the groove b and clear theouter end of the axle spindle.

It will be understood that any suitable number of arms 3 may beemployed. Four are here shown.

From the foregoing description, taken in connection with theaccompanying di'awings, the construction and opei'ation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention, as defined by theappended claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters-Patent, is,-

l. The hereindescrihed huh-attaching' device comprising a cap to heplaced in the outer end of a wheel hul), arlns pivotally connected tothe said cap having jaws for engaging with an annular groove iu the axlespindle and further provided with cam portions having outer' and innercam faces, an operating rod mounted in the cap, :i head attached to saidrod and connected to the said arms for engagement with the inner orouter cam faces oi said arms according' to the direction in which saidhead is moved. and a spring normally acting on said head to cause thesame to draw the inner ends of said arms toward each other and keep thejaws thereof in engage nient with the groove of the axle spindle.

2. The herein-descrihed huh-attaching device comprising a cup forattachment to the outer' end of a hub, arms pivotally connected to thesaid cap and having jaws at their inner ends to engage an annular'groove of an axle spindle, a head connected to the said arms and movablewith relation thereto, said head and said arms having coacting camdevices to cause said head to move said arms toward or from each otheraccording to the direction in which said head is moved. a spring to movesaid head in one direction, and means to move said head in the reversedirection.

In testimony whereof I have hereunto set my presence of two subscribingwitnesses.

JAMES lV. MAKLER.
